I, AUeUs'rE VASSEUX, a

and resi- Somme, France, useful Process for forth in the followin lhis invention relates to a 1process of treatin g by-products of sugar mi try, distilleries, fee

from molasses or ref in short of the bysolution both nitrogenous organic washing, taining in s, sugar industories extracting sugar use, of water from wool products conmatters and mineral matters.

The object of this the salts and the nitrogen. the previous renderin ganic matters and on t soluble salts.

tion -of the mass to remove invention is to recover It is based on insoluble of the ore subsequent lixiviatherefrom the The process is as'followsz- First the fluid products are concentrated .in an ap aratus, with or without ador neutralizin concentration is carried tothe ree of density, at

evaporatin dition of lime ble de Baum After the suitable them. The ighest possileast to 40 degrees tw o said concentration,

means can be used for rendering the organic matter almost completely insoluble.

concentrate can be 1. The treated with a concentrated acid, for instance sulfuric acid, in the pro ortion of 10 to 15 per cent. by weight,

which transforms it into a pasty mass, attacks the organic matters and renders them almost completely ture could be raised which they are that is to say, until insoluble. the concentrated products duced, without any suitable vats or kilns in 2. Or, if referred,

could he introaddition of acid, into which the temperato about 180 C. and in kept until sufficiently dried,

the matter acquires the then be ground. In pyrogenous reactions carried on slowly for about ten hours, also render the o anic matters almost entirely insoluble.

. After the treatment by concentrated sulfuric acid, the mass is mixed water to which may tioii of about 1 to 1 with ordinary be added, in the propor- 000 extract of gall nutinsolubility,

cachou, dividivi, tannin, sulfate of alumina, that is to say, products capable of rendering the organic matters still less soluble. In the case of the products which were simply] dried, they are mixed with water to wine has been added a sufiicient quantity of any acid, preferably sulfuric acid, inthe portion of about ten to fifteen per cent. 0 the mass, to bring about the combination with the existin' bases of the preexisting organic matters. yroligneous acid is also advantageous to use. i

The mixing gives inthe two cases a magna which is submitted to filtration in ordinary filter presses .or in suction filters.

B filtration are obtainedz-on the one han in solution, salts of potash and of soda which are separated by well known means; crystallization and concentration. On the ot er hand: nitrogenous organic matters which remain insoluble on the filters, in the conditions of the process, and from which water can be extracted and which can be dried.

I claim I .1

1. The process of manufacturingimanure and alkali salts which consists in concentrating organic by-products such as described, charring to enhance the insolubility of the organic material, lixiviating, and separating the nitro enous organic matter from the 'salts b tration.

2. T e rocess of manufacturing manure and alkali salts which consists in concentratin organic by-products such as describe charring, treating with dilute acid, and filtering. I

3. The rocess of manufacturing manure and"alkah salts which consists in semen tratin organic by-products such as do scribe treating with a concentrated acidffif enhance insolubility of the organicmatei'i washing with a dilute acid to further enhance and filtering.

In testimony whereof I have signed specification in the presence ing witnesses.
